Description

[Detailed description of the invention] The present invention has a structure that allows the lid to be fixed at the same time when installing a hand-wash faucet, etc. in a low-tank for flushing toilets (hereinafter simply referred to as a low-tank), which is equipped with a hand-wash faucet. It concerns low tanks.

Many low tanks are used in which a water faucet or spout pipe for hand washing is attached and the tank is used as a water supply tank for washing toilet bowls, and can also be used for washing hands at the same time.

In this case, the hand wash faucet etc. is fixed to the lid of the low tank, and the water supply to the hand wash faucet etc. is branched from the water supply pipe to the ball tap.
It was connected to a hand wash faucet, etc. with a pipe made of materials such as rubber or synthetic resin, and the lid was placed on the tank itself.

For this reason, carelessness during use may cause the lid to shift or fall off from the low tank body.

In addition, they sometimes fell off and were damaged during earthquakes.

In addition, during transportation, the lid requires a means for fixing the lid to the main body or is packaged separately, which is cumbersome.

The present invention has been devised in view of the above circumstances, and provides a low tank for flushing toilet bowls having a mounting structure that can securely fix the hand wash faucet to the low tank and at the same time firmly fix the lid to the low tank main body.

That is, in a low tank for flushing toilets with a hand wash faucet, etc. attached, a protruding piece is provided inward from the upper edge of the low tank main body, and a mounting bracket with a flow path connected to a water supply pipe penetrated inside is installed on the protruding piece. At the same time, insert the lid placed on the main unit, connect the hand wash faucet to the end of the take-out fitting, screw the union nut attached to the bottom of the hand wash faucet onto the take-out fitting, and hold the cover. This is a low tank for flushing toilet bowls, which is characterized by its high performance.

Examples will be described according to the drawings.

FIG. 1 is a perspective view of a low tank A according to the present invention, and FIG. 2 is a sectional view of the faucet mounting portion thereof.

The low tank A according to the present invention is composed of a main body 1 and a lid 2 placed on the main body 1.

A protruding piece 3 is provided inward from the upper edge of the main body 1, and a hole 4 is bored in the protruding piece 3.

A take-out fitting 5 is inserted into the hole 4 from the bottom to the top, and is secured to the projecting piece 3 by tightening with a nut 6.

The extraction fitting 5 has a flow path 7 therein, and thread grooves are provided at necessary portions on the outer peripheral surface.

Further, its length is such that it protrudes beyond the lid 2 placed on the main body 1.

A water supply pipe 8 for supplying water for hand washing, which is branched from a ball tap (not shown) at the lower end of the extraction fitting 5, is screwed into the extraction fitting 5.
Connect by adhesive, welding, etc.

A lid 2 is placed on the main body 1, and an ejection hole 9 is provided protruding from the M2 for inserting the mounting fitting 5. However, at the upper end of the ejection fitting 5, the flow path 7 is made slightly larger or not, and the inner periphery is closed. A groove 10 having a gear-shaped cross section is provided on the surface in the direction of the flow path.

On the other hand, the hand wash faucet 11 is attached to the extraction fitting 5, but the hand wash faucet 1
A union 13 is screwed onto 1 through a union nut 12.

The union 13 has a flange-shaped portion having a cross-shaped cross section, and the union nut 12 is locked to the flange-shaped portion.

At the lower end of the union 13, a protrusion 14 having a gear-shaped cross section is provided on the outer peripheral surface thereof, corresponding to the groove 10 provided in the mounting bracket 5.

The union nut 12 has a cross-sectional shape that encloses the protruding part of the extraction fitting 5 and the union 13, and has a mounting fitting 5 on the inner side of the waist.
A thread groove is provided so that it can be screwed into the thread groove provided on the outer peripheral surface of the.

To install the hand wash faucet 11, insert the union 13 into the mounting bracket 5, fit the protrusion 14 into the groove 10, and then screw the union nut 12 onto the mounting bracket 5.

Note that the extraction fitting 5 inserted into the extraction hole 9 is provided so as to protrude upward from the lid 2, so by screwing and tightening the nut 15 in advance, the extraction fitting 5 can be attached to the main body 1 using M2. It may be fixed via the

In addition, in this example, the hand wash faucet 11 is installed, but the same mechanism should be used when installing and using a water spout pipe that discharges hand wash water in conjunction with the opening and closing of the ball tap, as in the case of a normal low tank with hand wash. Can be done.

As described above, according to the present invention, since the low tank and the lid can be firmly fixed via the extraction fitting, it is possible to prevent the lid from falling off due to carelessness during use, and the lid will not be damaged.

Similarly, it is possible to eliminate the inconvenience of having to newly fix the lid during transportation.

In addition, the hand wash faucet is installed protruding from the low tank, but even if it is removed and packed during transportation, it can be installed and fixed at the installation location with the simple operation of inserting it from the top of the lid and tightening the union nut, which reduces shipping costs. It can be done to your advantage.

Furthermore, by providing grooves and protrusions that fit into the extraction fitting and union, the discharge direction of the hand wash faucet is determined uniquely, preventing rotation during long-term use, and making it possible to use the extraction fitting union in a stable condition. It is a device with great practical value, as it can be shielded by the union nut that contains it, making it look good on the outside.
